Definitions

  • the purpose of this invention is to provide a pump group for a vehicle cooling system, for example for an internal combustion engine, that satisfies the above-mentioned needs and overcoming the mentioned drawbacks.
  • the electric drive portion 34 is driven in rotation by the rotor 41 when the rotation speed of the rotor 41 is greater than the rotation speed of the shaft 13; in this case, the shaft 13 is driven in rotation electrically.
  • the pump group 10 comprises, preferably, a support plate 61 intended for the connection of the pump group 10 to the motor or to the motor support.
